- [Errors](https://developers.simcel.io/errors.md): Error codes and troubleshooting for the SIMCEL Insights API
- [Architecture Examples](https://developers.simcel.io/guides/architecture-examples.md): Common integration patterns with the SIMCEL Insights API at the center
- [Build Your First AI Agent](https://developers.simcel.io/guides/first-ai-agent.md): Use Python + OpenAI to build an AI agent that answers questions about your supply chain
- [MCP Integration](https://developers.simcel.io/guides/mcp-integration.md): Connect AI agents directly to SIMCEL docs and data using the Model Context Protocol
- [Scenario Comparison Patterns](https://developers.simcel.io/guides/scenario-comparison.md): Common patterns for comparing SIMCEL scenarios programmatically
- [Introduction](https://developers.simcel.io/introduction.md): Build AI agents and analytics on top of your SIMCEL supply chain data
- [Customers & Facilities](https://developers.simcel.io/master-data/customers.md): Read and override customers, distributors, and distribution centers in your network
- [Get Customer](https://developers.simcel.io/master-data/customers-get-one.md): Returns full details for one customer by their facility reference.
- [Get Facility](https://developers.simcel.io/master-data/facilities-get-one.md)
- [List Facilities](https://developers.simcel.io/master-data/facilities-list.md): Returns all facilities in the network — customers, secondary customers, distributors, and distribution centers (DCs).
- [Override Facility](https://developers.simcel.io/master-data/facilities-patch.md): Creates or updates a local override for specific facility fields. Only the fields you include will be overridden.
- [API Overview](https://developers.simcel.io/master-data/overview.md): Read and override your SIMCEL reference data — products, pricing, customers, and facilities
- [Product Values](https://developers.simcel.io/master-data/product-values.md): Read and override product pricing per customer — GSV, listed price, with effective date ranges
- [Upsert Product Value](https://developers.simcel.io/master-data/product-values-post.md): Creates or updates a pricing override for a product–customer–type combination.
- [Products](https://developers.simcel.io/master-data/products.md): Read and override your product catalog — packaging, logistics, and classification attributes
- [Get Product](https://developers.simcel.io/master-data/products-get-one.md): Returns full details for one product by its ID.
- [Override Product](https://developers.simcel.io/master-data/products-patch.md): Creates or updates a **local override** for specific product fields. This does not modify the source master data — it writes to SIMCEL's override layer, which takes precedence in simulations that use this workspace.
- [Quickstart](https://developers.simcel.io/quickstart.md): Make your first SIMCEL API call in under 5 minutes
- [Rate Limits](https://developers.simcel.io/rate-limits.md): Request limits and best practices for the SIMCEL Insights API
